Title: Geometric vector quantization
Inventor: JACQUIN ARNAUD E
IPC: H04N19/94
Filed: 1993-01-25
Granted: 1998-09-01
Abstract: A geometric vector quantizer coding technique is illustrated in the context of a full motion video coder based on a three-dimensional sub-band framework. The original image data is decomposed into different spatial-temporalfrequency bands and based on the data in each band, different quantization strategies are applied to the bands. The lowest spatial-temporal frequency band is coded using a traditional three-dimensional switched predictor and optimum scaler quantizer.The non-dominant sub-bands are coded using the vector quantization approach to efficiently encode the images while appropriately exploiting the sparse, highly structured nature of the data to design the codebooks. Variable resolution is achieved using these techniques and no training is needed to establish or maintain the codebook. A fast codebook search technique is provided for identifying the optimal codebook vector for representing a block of input data. Examples of two and three level geometric vector quantizers are also provided.

Title: Synthetic aperture array dipole moment detector and localizer
Inventor: LO ALLEN K
IPC: G01R33/24
Filed: 1993-04-07
Granted: 1998-09-29
Abstract: A synthetic array comprising a moving magnetic sensor that provides a signal representative of an array of magnetic sensors is coupled to a digital signal processor is used to break a magnetic dipole field into its components, and a magnetic, signature of the present magnetic field is created. Predicted dipole signatures are precomputed for multiple magnetic orientations of the dipole at each of a plurality of range locations, expressed in terms of Anderson functions, which are a set of equations that decompose the magnetic field in each of the magnetic response locations, and are stored in a lookup table for reference. Input data measured by the moving synthetic array are processed and each magnetic value is predicted to process against background noise. A long term time average consistent with the relative motion of the dipole is computed using band-pass filtering of the signals from the synthetic array. The bandpass filtered data is used to update the predicted data so that anomalies and other non-dipole data is removed from the signals that are processed. The data are then expressed in terms of Anderson functions. The data are matched filtered, wherein it is correlated with the stored pre-computed predicted dipole signatures. The correlation yields a set of values that is then thresholded. If a dipole is present at any of the locations, then the correlated normalized value computed as stated above will be higher than the chosen threshold. The dipole locations that are above the threshold are then displayed on a monitor showing the relative location and dipole orientation.

Abstract: An enclosure for heat generating electronic components establishes an airflow path for cooling air.  Air is forced through the enclosure by powered air movers, one of which is mounted at the air inlet to the enclosure, and the other of which is mounted at the outlet.   Preferably only one air mover is used at a time.  In the event of failure of the air mover being used, the remaining air mover begins operation. The total cooling airflow passes through both air movers, and thus the air movers may thus be said to be arranged in series with respect to the airflow.  Because the air movers are mounted in  series with respect to  the  airflow,  the airflow pattern  is  substantially  the  same  regardless  of which air mover is currently operating.   Thus,  hot spots which may result when one  fan in a  fan bank fails  are avoided.  In the preferred embodiment, the enclosure houses a redundant array of independent disks (RAID) of a computer system.  In an alternative embodiment,  air movers arranged serially with the airflow can be used to provide additional cooling for severe operating conditions.

Abstract: The sensitive detection of explosives and narcotics by nuclear quadrupole resona nce (NQR) is performed at low rf power by assuring that the rf field strength is larger than the local magnetic field. Additionally, it has been recognized that signal-to-noise ratio of a signal induced by a specimen of fixed size decrease b y only the square root of the coil size. Thus, rather than scaling power linearly with coil size, as conventionally done to maintain the sa me rf field intensity, the power needs only be increased by the square root of the increased coil size to assure maintenance of the same signal to noise ratio. This technique permits the use of larger coils than previously used. The invention is useful fo r both volume coils and surface coils.

Abstract: In a code-division multiple-access automobile on-board and/or portable telephone system capable of increasing the capacity of subscribers easily on the basis of changing of information transmission bit rate, spread codes obtained by multiplying orthogonal spread codes (m in number) by a pseudo-random noise series are assigned to individual channels in the same cell in such a manner that the orthogonal spread codes are multiplied by some types of pseudo-random noise series having different phases, thereby making it possible to maintain the number of channels in the same cell at a value which is a multiple of the number of the orthogonal spread codes. Through this, in the case where the transmission bit rate is halved as compared to the presently existing rate in the future, assignment of spread codes which are increased in number to as large a value as necessary can be achieved and the subscriber's capacity can be increased within a range in which the necessary quality can be maintained even when link paths for m or more channels are set up in one cell from the viewpoint of SIR.
